polyester是好面料吗?

Question

如题所述

Answer 1

1. Polyester, commonly known as涤纶, is not generally considered a superior fabric choice.
2. When compared to natural fibers, polyester has several drawbacks including low moisture content, poor breathability, subpar dyeability, proneness to pilling, and ease of soiling.
3. To address these issues, chemical modification and physical deformation techniques are employed.
4. Polyester fibers find increasing application in various industries, agriculture, and emerging technologies. They are used in products such as tire cord, conveyor belts, ropes, and electrical insulating materials.
5. Polyester tire cord yarn boasts high strength and initial modulus, as well as excellent heat resistance, fatigue resistance, and shape stability, making it particularly suitable for tire cord production.
6. The use of polyester tire cord in tire manufacturing can lead to a reduction in flat spots.
7. The production of polyester staple fibers involves a series of processes: spinning multiple filaments together, wetting and oiling them, collecting them in a drum, and then subjecting them to bundling, stretching, twisting, heat setting, and cutting to produce the final product.
8. If the stretched fibers are subjected to a tight heat setting process at around 180°C, they can achieve strengths above 6 cN/dtex and elongation rates below 30%, resulting in high-strength, low-elongation fibers.
9. Polyester staple fibers are categorized into cotton-like fibers (38mm in length) and wool-like fibers (56mm in length), each designed for blending with cotton or wool, respectively.
